2010 E70 X5 - Squeaking Noise from rear of car

[Sm[]key]

My car has been suffering from a ‘squeaking’ noise when travelling and is noticeable when a low speeds with windows open.

I assumed it was my rear heat shields under the boot moving, I removed these however the squeaking is still there.

I jacked the rear up and took the wheels off, and used a long bar to replicate movement when driving but nothing seen.

Any ideas what the issue could be?

Rear rose bushes with the suspension inflated nothing moves try standing on the sill and rocking the car side to side
The next symptom will be increased camber and inner tyre wear

Well the squeaking noise is much worse now, got someone to jump up and down on the sill whilst under car, not sure if its:

- Shock Absorber
- Air suspension
- Shocker arm
- Control arm bush

The noise is that loud its very hard to locate.

I know before one rear air spring was changed it did squeak a bit but your noise sounds like its louder than mine was

Further investigation started this afternoon, started with the shock damper.

Not the easiest to get to when you have two extra rear seats in the boot!

The centre of the damper does not appear to be central to the mount, I'm guess this is not normal and could be my squeaking problem? A lot of ground dust can be seen in the photo....

Anyone with experience of this?

Had a look at the parts list on realoem, it would appear the bushes have disintegrated.
